FS#4246 - x86: AMD embedded SFP+ amd_xgbe no link

[openwrt-bot]

pmisch:

I wish to add a new device which "should" be supported but isn't in the list, yet.
It's a Deciso DEC740 with an AMD SoC v1500b. There is also the DEC750, DEC840 and DEC850 which are similar.

There were two commits regarding that SoC:
37958f0
1c4cd71

OpenWrt Nightly starts without errors. In dmesg I can see those lines:
[ 9.723673] kmodloader: loading kernel modules from /etc/modules.d/*
[ 9.734152] libphy: amd-xgbe-mii: probed
[ 9.739298] amd-xgbe 0000:06:00.1 eth3: net device enabled

root@OpenWrt:~# cat /etc/openwrt_release
DISTRIB_ID='OpenWrt'
DISTRIB_RELEASE='SNAPSHOT'
DISTRIB_REVISION='r18681-5d110c0161'
DISTRIB_TARGET='x86/64'
DISTRIB_ARCH='x86_64'
DISTRIB_DESCRIPTION='OpenWrt SNAPSHOT r18681-5d110c0161'
DISTRIB_TAINTS=''

The problem is the links won't come up, no matter what I do . I tried to configure the interfaces in /etc/config/network or via "ip link set up eth3" but nothing happens, even no logs.
When I boot the Hardware with OPNsense (which is the stock firmware for those) the links come up fine.

I recompiled my own image and now it seems to work after fiddling around a bit with ethtool. This can be closed, sorry for bothering.
